Rehabilitation Exercising Equipment that can Extend a User's Waist and Back

Abstract

A rehabilitation exercising equipment includes a main frame, a seat mounted on the main frame, and a pivot mechanism pivotally mounted on the main frame and pivotable relative to the seat. Thus, when a user is seated on the seat, he/she can apply a force on the pivot mechanism to pivot the pivot mechanism backward and forward so as to extend and contract the user's waist and back, thereby achieving an exercising or rehabilitating function.

         12 . The rehabilitation exercising equipment of  claim 10 , wherein
 the support post of the main frame has an upper end provided with two transverse mounting shafts for mounting the pivot mechanism pivotally;   the back support bracket of the pivot mechanism is provided with two pivot members pivotally mounted on the main frame;   the two pivot members of the back support bracket are rotatably mounted on the two mounting shafts of the support post respectively.   
     
     
         13 . The rehabilitation exercising equipment of  claim 2 , wherein
 the back support bracket of the pivot mechanism has a substantially inverted U-shaped profile and has two distal ends connected with the arm support bracket;   the arm support bracket of the pivot mechanism has a substantially U-shaped profile;   the arm support bracket and the back support bracket of the pivot mechanism are combined to form a substantially L-shaped structure.   
     
     
         14 . The rehabilitation exercising equipment of  claim 10 , wherein
 the rehabilitation exercising equipment further comprises a transmission mechanism mounted between the main frame and the pivot mechanism;   the transmission mechanism includes:   a drive geared member connected with the pivot mechanism to move in concert with the pivot mechanism;   a drive unit mounted on the main frame;   a driving geared member rotatably mounted on the drive unit; and   a linking member mounted between the driving geared member and the drive geared member to link the driving geared member and the drive geared member.   
     
     
         15 . The rehabilitation exercising equipment of  claim 14 , wherein
 the back support bracket of the pivot mechanism is provided with two pivot members pivotally mounted on the main frame;   the drive geared member of the transmission mechanism is secured on moved in concert with one of the two pivot members of the back support bracket and is rotatably mounted on the support post.   
     
     
         16 . The rehabilitation exercising equipment of  claim 14 , wherein
